Use change of base to rewrite the expression, log5 16

When I solved this, I got log10 16 / log10 5

But when checking it on mathway I got log 16 / log 5

Could someone explain this?

1. it's a semantics thing ... if no base is indicated , 10 is assumed

2. the base does not matter. logb16/logb5 = log516

here is the question: log5(x-4)= log7x solve for x. These are just base 10 logs. log100 = 2 This equation has the same format as log 40 = log (2x20) Since both sides have log base 10, you divide by log base 10 and end up with
